Longhorns at Tonna

Sheltered clearing (SS78199948)
 I found a very impressive area today next to the Neath canal near the Aberdulais Basin. Having already seen a Black-and-yellow Longhorn before I reached this area I thought the density of umbellifers here would be worth a closer look. Longhorns like the flat inflorescences which provide easier areas to land and take-off. Those landing platforms in this case provided by Hemlock Water-dropwort (Oenanthe crocata).
Black-and-yellow Longhorn Beetle (Rutpela maculata)
 At least 6 Black-and-yellow Longhorns (5+ in this clearing) were the most numerous species noted.
Speckled Longhorn Beetle (Pachytodes cerambyciformis)
 I was amazed to find 2 further species of Longhorn also in this clearing. 2 Speckled Longhorns and 1 Black-spotted Longhorn completed the tally.
Black-spotted Longhorn Beetle (Rhagium mordax)
All 3 species have widespread distributions in Wales in or near to wooded areas.

Also seen today a Beautiful Demoiselle (Calopteryx virgo) near the carpark area at Aberdulais Basin. Photo of this can be found following the link below

Great series of captures Mark. Speckled Longhorn is pretty scarce in the west here I believe and quite a nice plant record too!

Thanks Barry. I was like a kid in a sweetshop. You may have noticed that for a while the umbellifer was identified as Hemlock. A very nice record indeed, unfortunately completely wrong!
I think the saying goes "close but no cigar!"
